McDonough County

McDonough County sits at the cash-flow end of the spectrum, and the numbers make that unambiguous. At a median home price of $99,184 and median rent of $918.75, the gross rent-to-price ratio is 11.1%, which is well above the 8% threshold most investors use to distinguish cash-flow markets from appreciation plays. The model underwrite bears that out: a 7.22% cap rate at a 6.85% interest rate means the property earns above its financing cost on an unlevered basis, a condition that is genuinely rare in most US markets right now. Cash-on-cash comes in at 4.05% with 20% down, and estimated monthly cash flow of $77 is modest in dollar terms but positive, which matters when you consider the all-in purchase price is under $100,000. Home price appreciation is effectively flat, 0.5% year-over-year, so you are not buying this county for price growth. You are buying it because the rent-to-price math works, the entry price is low enough that a single tenant covers the note, and the affordability index sits at a perfect 100.

This market is built for the cash-flow buyer and the capital-constrained investor who wants to own multiple doors without concentrating a large amount of capital in any single asset. At $99,184 median, an investor with $100,000 in deployable equity could acquire five properties at 20% down and still have change left over for reserves. The appreciation score of 55 and stability score of 50 tell you this is not a market where you are relying on exit value or long-term demographic tailwinds to make the deal work. The deal has to pencil on income alone, and here it does. Value-add operators can also find opportunity at this price point because the spread between distressed acquisition and stabilized value does not need to be large in dollar terms to be meaningful in percentage terms, and local competition for properties is likely limited given the county's size and relative obscurity to institutional buyers.

McDonough County is home to Western Illinois University in Macomb, the county seat, which is the central economic anchor for the area. A university presence of this kind creates a structural floor for rental demand, specifically student housing and housing for faculty and university staff, that is less correlated with private-sector employment cycles than a typical small county of 27,370 people would be. That demand profile supports the rent levels reflected in the data and gives a landlord a recurring tenant pool that refreshes annually. The tradeoff is that university-dependent markets carry their own concentration risk, discussed below, but the anchor also explains why a county this small can sustain a rent-to-price ratio that outperforms counties several times its size.

The property tax situation in Illinois deserves serious attention before you commit capital here. The state-average effective rate used in this model is 2.27%, which the Tax Foundation flags as very high, and that translates to $2,251 in annual property taxes on a $99,184 asset, or $188 per month. Combined with the estimated $22 monthly for insurance, your tax-and-insurance carry is approximately $210 per month before you touch the mortgage. On a gross rent of $919, that is roughly 23 cents of every rent dollar going to taxes and insurance alone. At 2.27%, that rate needs its own line on your underwrite and should be stress-tested against the actual county and township rate, which can differ materially from the state average. Illinois is a state where county-level property tax rates vary widely, and McDonough County's rural character does not guarantee a lower rate than the state average. Verify the actual assessed rate with the county assessor before closing, because a rate meaningfully above 2.27% compresses the already-thin monthly cash flow of $77 quickly toward zero.

The primary risk in McDonough is concentration, specifically the reliance on Western Illinois University as the dominant economic engine. University enrollment trends, state funding decisions for public universities in Illinois, and any structural decline in the college-age population in the Midwest could each affect occupancy and rent levels. The stability score of 50 reflects this. A county of 27,370 with a single institutional anchor has limited diversification, and if that anchor contracts, there is no secondary employment base of scale to absorb the demand. Investors should size their exposure accordingly and monitor enrollment data annually as a leading indicator of rental demand.

Against the comparable counties in this dataset, McDonough's differentiation is purely on price and cash-flow yield. Sangamon County prices at $186,233 with a rent-to-price ratio of 7.3%, Winnebago County prices at $195,413 with a ratio of 7.4%, and both carry the same overall score of 76 as McDonough. You are paying roughly twice the acquisition cost per door in those counties for a rent-to-price ratio that is 38% lower. Pike County is the closest in price at $112,450 but carries a slightly lower overall score of 75 with no rent data provided to evaluate the yield directly. An investor should choose McDonough over its neighbors when capital efficiency is the priority, when the goal is maximizing the number of doors acquired per dollar deployed, and when the investor is comfortable with the university-concentration risk and the Illinois property tax environment. An investor should favor Sangamon or Winnebago when they want a larger, more economically diversified market and are willing to accept a lower cash-flow yield in exchange for that stability.
